4 Claims.- (Cl. 242-18) This invention relates to a multiple yarn package unit and more particularly to an apparatus for winding a plurality of individual yarn or filament bodies upon a single tube.

An object of the invention is to provide an apparatus which will simultaneously build up a plurality of yarn bodies on a cylinder or tube enabling the several bodies to be handled as a unit during the steps of after-treatment or in subsequent processing.

A further object of the invention is to construct such an apparatus that the several individual yarn bodies will be built up simultane-v ously and uniformly on the winding cylinder or tube.

A still further object of the invention is kthe provisionof a simple and novel means for supporting the unit while the bodies are being built thereon, with means to facilitate the insertion and removal of the unit from its driving connection and to hold the unit supporting -means in elevated .position for .ready removal .of the unit or insertion of a new cylinder.

These and other objects will become apparentfrom the following detailed description of the apparatus.

Referring to the drawings it will be seen that Fig. 1 illustrates a top plan view of one complete section of the apparatus; Fig. 2 is a side elevation of a complete section;

Fig. 3 is a top plan view showing one of the units partly 'in cross-section;

Fig. 4 is an end elevation illustrating the unit v' invention," the'drawings disclose one complete section of a machine which may be made up of any desired number of sections or units h orizontally Aarranged -on an elevated frame work.

Extending throughout the length of the main,- frame A of the machine are two suitably supported vertically spaced vparalleltubes or rods, I and 2. Each sectionor unit of the machine is hung or supported from these rods and each section'includes a pair of spaced brackets 3 whose sidesl are contracted and held in close contact with the pipes I and 2 by means of bolts. A t the 1 upper-ends of the -sides of the brackets 3 and mounted on spaced parallel rods l are oppositely extending pivoted arms5 aperturedfor the reception of headed bolts 1*, the rods 4 passing through journals 6 formed in the upper ends of the brackets 3. It will be observed that each side of the section is identical and a duplicate of the other and it will, therefore, only be necessary to describe the mechanism of one side to comprehend the mechanism used on the other side..

Outwardly extending lugs 3a are formed on opposite side portions of the brackets `3 and are horizontally apertured to receive pivot shafts 8 on which are hung bell-crank levers 9. These they terminate in a step or latch II', as will be explained hereinafter. The step or latch II cooperates with a pin I2 placed pn the inside of the lever arms 5 to hold vthe saine in elevated polevers 9 normally lievbelow and parallel to upper sition -when the parts cooperate. The headed I bolts 'I passing through the levers 5 extend inwardly toward oneanother and form in effect, a

pair of stub axles. Referring specifically to the right hand portion of the section, see Fig.'3, it will be noted that a .pair of ball bearings I3 cooperate with grooves I4 formed in a ring member 32 supported on the shank of bolt I and that these bearings in turny support a circular disc I5 held for rotation therewith by means of end'cap I6.. A circular groove- IT is formed on the inner face of the disc I5 for theA purpose of supporting the end ofa winding vroll or tube `as hereinafter described.

Referring now to the left hand portion of the unit illustrated -in Fig. 3, it will be seen that here the shank of the bolt I while slightly longer than the bolt on-the right hand section also acts as a stub axle. A pair ,of slightly spaced apart ball bearings I3 are mounted on the shaft portion of the bolt interiorly of anged bushing I8 and anend plate I9 -is secured to the outer end of thebushing and rotates therewith. I'he ends of the coil spring 20 encircling the bushing I8 rest in grooves 2| and 22- formed in the plate I9 and disk 23. This .disk 23 is mounted exterior` ly of thefbushingl and isadaptedfor sliding movement therealong against the tension of thespring 20. The inner'face of the disc 23 is provided with an annular groove 24 similar to' groove I1 in opposite vdisc I5 for supportingV therebetween a perforated expanding windingl cylinder or tube 25. This winding tube 25 maybe'of any suitable construction Aas long as it' exerts a slight outward 'expanding tension, and in the form illustrated comprises a split metal-- lic cylinder having slightly overlapping edges;

Also carried by the -main machine frame A are-pairs of driven live rolls 26 having frictionsurfaces 21 for driving contact with the cylinders 25 and .the yarn bodies built up thereon. 'I'hese live rolls are driven by any suitable pqwer means s uch as a chain and sprocket 28 mechanism to transmit power-to the shafts 2 9 connected together by means of gearing'30.-

, The apparatus thus described 1s of great value 'I in winding a multiple package ofindividual yarn V iilai'ent or thread bodies and nds its application in textile winding machines although it is of particular value in the artilicial silk industry. Here, delicate filament or thread bodies are wound on individual perforated contractible spools, and while still on the spoolsvare aftertreated in Yvarious chemical and Washing baths after which the yarn is dried and removed from the holders. It has been found that any manual handling of artificial silk bodies is most detrimental. to them, and as each individual package or body must be separately handled for each of the several steps a large amount of material is thus damaged. With the present invention it is possible to wind a plurality of uniform packages or bodies on a single perforated tube and the whole handled as a unit and thus minimize spoiling of the delicate iilaments.

As before described the tube or cylinder on which the several packages are built up is constructed to exert a slight outward tension on the package to insure that the package will hold its form and not be allowed to unravel or become loose. The use of such a. contractible tube or cylinder also compensates for any subsequent shrinkage of thev package. 'I'he apparatus as herein disclosed, not only permits the simultaneous winding of a plurality of uniform bodies on a single tube but also permits the tube to be readily inserted in or taken from the apparatus. It will be observed that when it -is desired to wind a plurality of yarn packages B a cylinder may be quickly and easily inserted in the machine by pressing laterally the movable end disc 23, and after centering the opposite end of the tube inthe groove in the disc 15, the disc 23'is tted over the opposite end of the cylinder and thus retained in position through the medium of the tension of the spring 2l. When tubes are inserted in the machine the levers 5 and 9 are in elevated position as shown in Fig. 5, the bellcrank lever 9 having dropped downwardly of .its own weight-and the p in I2, carried on lever 5 has engaged the latch or step Il. 'Ihe new tube to be wound may then be placed in driving connection with the driving rolls 2B by merely raising the end or handle of the lever 9 to cause the latch I I to disengage the pin' l2 and allow the tube to drop downwardly until it, contacts the drive roll. Conversely, when a tube is full of yarn bodies B and it is desired to remove the unit, the operatorv elevates the lend or handle of the lever 5 to cause the bell-crank 9 to pivot downwardly of its own weight and engage the latch and pin mechanism, whereupon thedisc 23 is pressed outwardly and the entire unit carrying its several yarn bodies B is readily removed.

The manipulation of thedevice is greatly facilitated by reason of the close proximity at the outer face of the machine of the` handle provided on the lever 5 which is operated to disengage the winding .tube from the drive roll and of the handle provided on the 'lever 9 which is operated to disengage the locking means and allow the winding tube tov move into contact with the drive roll.

To insure that the cylinders 25 and the yarn' bodies being built up thereon will rest against the drive rolls at the Aproper driving tension, a coil spring 3| is positioned around the rods 4l 'to which the levers 5 are secured. The springs 3l aflixed between stops 33 and journals 6 rotate with the rods 4 and levers 5 and thereby proper tension is secured by adjustment of stops 33.

While I have described nur improvements in levers, the smaller of which rests great detail and with respect to preferred forms` thereof, I do not desire to be limited to such y details or forms since many modiiications and changes may be made and the invention. embodied in widely diierent forms without departing from the spiritand scope thereof, in its broader aspects. Hence I desire to cover all modiiications `and forms coming within the language or scope of any one or more of the an pended claims.
